So far in this unit we've seen equations that have one variable (on one side of the equation) that we need to solve for using inverse operations. However, not all equations look like this. Sometimes we will see equations that have variables on both sides of the equation. For example:
3x + 9 = x - 7
When we have variables on both sides of the equation, we have an extra step when solving the equation. First, we need to get the variables together on one side of the equation (it does not matter what side you put the variables on). Then, we can solve the equation like we've been doing throughout this unit using inverse operations. Here's an example:
